HI, using this functions images lose colors and they display mainly grey colors also using ImageConverter 565 v2.3 tool the same.
For example I have one with a red background and white text/icon and the background becomes grey.
Using other library they work ok.

Found the problem.
The manufacturer advertise wrongly the IC driver, it was not a HX8357B, but a ILI9486.
As soon I switch to this IC on the User_Setup.h file, all started to work perfectly.
